For the 2015 CPS ASEC geographical mobility package, the metropolitan mobility detailed tables 14 through 16 are not included. The U.S. Census Bureau is currently transitioning to a new sample design for the CPS based on the 2010 Census. During this period, the CPS estimates are based partly on the 2000 sample design and partly on the new 2010 sample design. As a result, metropolitan-nonmetropolitan estimates from the 2015 ASEC are based on samples of two different designs, and do not accurately reflect the actual respective populations and will not be provided during this period.
